Culture conditions:
- Xenic: with small inocula of E. coli on 1% soil agar (incl. 1-3%
dark soil) + 5 µg/ml cholesterol. Any excess moisture on plate surface
is allowed to evaporate before sealing. Other bacteria and a fungus have
not been removed. Kept at 17C.

Identification:
Paul De Ley.
Notes:
Males are common in some plates, absent in others. Only three juvenile
stages, each of which is characterized by a distinctly different head morphology.
During feeding, juveniles and adults swing their head dorsally and ventrally
like metronomes.
